The ocean and the Blue Economy are increasingly top priorities worldwide. The immense ocean territory in the planet and its huge associated economical potential is envisioned to increase the activity at the ocean in the forthcoming years. The support of these activities, and the convergence to the Internet of Things paradigm, will demand wireless and mobile communications to connect humans and systems...
The Internet of Things (IoT) is a vision for interconnecting all of the world's "things" -- from vehicles to diet scales, smart homes and electrical grids -- through a common set of networking technologies. Realizing this vision using a host-to-host communication paradigm, such as that of the Internet Protocol (IP), is challenging in the context of highly heterogeneous, constrained devices...
Maintaining communication among the population, during and in the aftermath of disasters, is key to the success of both response and recovery efforts. Evidently, the telecommunications infrastructure most often fails in these situations and thus adhoc solutions ought to be devised. However, unlike customary adhoc solutions that focus on the traditional end-to-end communication paradigm, in emergency...
The growing demand for mobile content has increased the burden on cellular network providers. To this end, mobile content offloading approaches aim to offer a relief of overloaded cellular network infrastructures via local content exchanges between mobile devices. A core assumption of proposed approaches is the voluntary, honest, and altruistic participation of devices or their owners. This dependency...
The wireless internet service is offered to the people through Wi-Fi technology in commercial and industries. It is working based on radio waves in the spectrum. These waves are very harmful to the diseased people, signal sensitive areas. Hence it could not be utilized in environments such as hospitals, scan centers, air lines etc. To overcome these limitations, Li-Fi is the technology that is developed...
Large-scale disasters, such as earthquakes and tsunamis, damage communication infrastructure. The damaged infrastructure is then not able to provide the means for communication, which is important after a disaster. In this paper we simulate how survivors of a disaster can place smart phones or notebooks (hereafter called devices) as stationary relay chains to connect to other evacuation centers and...
Internet of Things (IoT) is the connection of the physical world to the Internet. It is fast emerging as the sustainable solution for providing access to affordable and clean energy all around the world. The utilities with IoT can have real-time feedback capabilities to better understand the customer needs and therefore make intelligent decisions to improve their service experience. With IoT, the...
Machine-to-machine (M2M) applications are expected to be the main traffic contributors through the Internet of Things (IoT) paradigm. One of the most prevalent communication access technologies is Wi-Fi. While open Wi-Fi hotspots can be easily used by M2M communications of static or mobile devices, this is not the case for private Wi-Fi installations that are normally secured against unauthorized...
Machine-to-Machine (M2M) communications are expected to be the main contributor of traffic over the Internet by the time frame of the launch of 5G. Wireless access via a cellular infrastructure is expected to be the main M2M traffic passage into the Internet. Long Term Evolution (LTE) is the main cellular technology for 5G. The method by which user devices are normally allowed to attach to an LTE...
Existing spectrum is unable to support explosive demand of voice and data traffic. Day by day data traffic usage is exponentially demanding higher bandwidth. Existing spectrum is already assigned to various services like mobility, fixed line internet (GSM, WCDMA, LTE), etc. New spectrum to address the increase in demand is not available. Hence there is a need for alternate spectrum. However, no alternate...
The paper discusses utilisation of the brute force methods for the task of towers distribution in wireless communication systems. The proposed algorithm allows to find an optimal allocation of a tower between the settlements. A simple wireless communication has been used as an example to investigate the functionality of the algorithm's software.
With the rapid development of wireless communication technology and mobile devices, network traffic on smart mobile devices has increased gradually. VoIP is a well-known and mature technology and communication anywhere is emerging as an important application that requires an entirely different way of thinking about communications. In practice VoIP system one kind of issue that vitally impacts the...
A multichannel wireless mesh network is composed of wireless routers with multiple radio interfaces operating on non-overlapping channels. It provides a network backbone to support multi-hop connectivity between wireless users and the Internet gateways. However, robustness is a critical issue in such networks because wireless links could be prone to error. Simulation results show that the proposed...
The popular method for MANET to access the Internet is choosing some gateways through which MANET can act as a subnet of the Internet. In these solutions, gateways will be the bottleneck of the whole network. Meanwhile, gateway selection and handoff are also the problems. Since aforesaid problems, a new protocol was implemented on embedded devices based on iAODV, and route optimization and link failure...
in television white space networks, secondary users are mandatory to query an accredited geo-location spectrum database (GSDB) in order to determine the vacant channels or white spaces. The recent developments of the Protocol to Access White Spaces (PAWS) by the Internet Engineering Task Force (IETF) have proposed to standardize communication between the GSDB and white space devices. To enable efficient...
This paper considers the task of deploying mobile wireless repeaters on aerial vehicles in the upper air of Earth to increase the Internet connectivity of users with little to no network infrastructure. By routing data between a user and a strong connection to the Internet through the vehicle network, this ad hoc infrastructure can provide Internet access to those currently without it. We consider...
This paper presents a smart NFC and Wi-Fi enabled clock. The smart clock presented in this paper is designed in a way that it connects to the Internet using Wi-Fi module, which enables it to read information to and from the cloud. The NFC chip embedded in the smart clock enables it to communicate with other NFC enabled devices, e.g., smart phone and passive tags which lets it perform tasks on the...
In this article, we construct a concrete model as the prototype of efficient and reliable wireless Information Centric Networking (ICN) within the context of Intelligent Transport System (ITS). This research proposes a novel proactive-caching technique in ICN providing the robust and effective content delivery to the mobile nodes (commuters) for transportation system and fitting numerous ICN mobility...
In emerging non-safety unicast applications of vehicular ad hoc networks (VANETs) such as Internet Access, Content, Map, or Database Download (CMDD), end-to-end and connection-oriented transmission control must be employed to guarantee a desired level of performance. It is envisioned that in the future, these non-safety applications will involve several concurrent flows. Providing a fair distribution...
Aiming at the problem that the existing GPRS monitoring system has no signal in some areas and the expensive price, an on-line monitoring system for transmission line based on 6LoWPAN technology is proposed. 6LoWPAN technology has built a bridge for communication between the wireless sensor and the Internet for the system, and achieved data collection, analysis to the transmission line temperature,...
